超声波/紫外线-Fenton反应联用去除克拉玛依土壤中石油类污染物
Removal of petroleum from soil in Qaramay using ultrasound/ultraviolet-Fenton reaction
摘要
Abstract
The ultrasonic-Fenton reaction and ultraviolet-Fenton reaction were combinedly used to remove total petroleum hydrocarbon（TPH） from soil that was heavily contaminated with TPH（30 470 mg/kg） in Qaramay oil field.Under conditions of pH 3 and H2O2/Fe2＋=50∶ 1,addition of 0.37%,0.74%,1.11% and 1.85% H2O2 caused 4 495,11 983,15 470 and 19 800 mg/kg TPH removal,respectively after 6-hour ultrasonic-Fenton reaction.TPH removal efficiency increased with increasing H2O2/Fe2＋.When H2O2/Fe2＋ was 100∶ 1,the TPH removal was 12 699 mg/kg.The ultrasonic and ultraviolet were combinedly used to assist the Fenton reaction.At neutral pH and 0.74% H2O2,4 hours of ultrasonic-Fenton reaction and ultraviolet-Fenton reaction caused TPH removal of 21 821 mg/kg and 12 845 mg/kg,respectively.GC-MS analysis showed that the 1,2-dimethylbenzene could be more efficiently removed than the linear paraffin and branched paraffin and the aliphatic hydrocarbon derivates were most resistant to decomposition in the ultrasound-Fenton reaction process.关键词
